Google hands publishers a button to fight AI search traffic loss

The AI search traffic squeeze is now a two-front story: Google is handing publishers a lifeline that may be mostly symbolic, while the AI-agent gateway market gets messier as a startup and its former tester settle their fight in court — and in the product aisle. Google is handing publishers a new "Preferred Sources" button they can embed on their own sites, letting readers mark them as a favorite source that surfaces more often across Search, Discover, and Google News. The move is Google's most

Grok keeps sending gibberish responses to users

An xAI generation glitch is turning Grok into a word-salad machine for some users — and the company's own status page still insists nothing is wrong. xAI's Grok chatbot has been replying with pages of incoherent gibberish to a subset of users, with the failures concentrated in the free Grok Lite tier and surfacing as early as Wednesday morning. One user who asked Grok to generate a PDF got back "match it without and your they and two for planets can practical and often cheese…" with the nonsens

Ramp launches its own AI model router

Two moves today point at the same prize: whoever sits between you and the model gets paid. Ramp is building the toll road, while Liquid AI is making the smaller models running on it go faster. Expense-management fintech Ramp just opened its own AI model router, letting developers and companies route prompts across OpenAI, Anthropic, DeepSeek, and more through one API. The service, called Router, launched Wednesday evening and is available only in the United States; it is free to use through the

Tesla's Austin robotaxis go driverless, and nobody will confirm it

Seven months after Elon Musk claimed Tesla's Austin robotaxis were running without human safety monitors, a crowdsourced tracker says the city's service has finally gone fully driverless. The catch: Tesla still won't say so itself. What actually happened Over the past two weeks, every one of the 170 Tesla Robotaxi rides in Austin tracked by the volunteer-run Robotaxi Tracker ran with no human safety monitor onboard, the site's creator, Ethan McKanna, told The Verge. Those rides spanned 54 dif

Mistral launches Agentic Search for complex documents

Two moves today show AI shifting from flashy demos to the unglamorous plumbing that actually makes models useful: a retrieval layer that reads inside dense filings, and Tesla quietly pulling humans out of its robotaxis. Mistral's new Agentic Search turns RAG from a single guess into a multi-step investigation. The company launched Agentic Search on August 20, a retrieval layer that lets an AI system navigate, open, read, and verify information inside long, table-heavy documents instead of answe

China's LLMs quit the price war as DeepSeek API jumps 11x

China's AI labs are closing the book on the "cabbage price" era — the two-year race to give away model inference is reversing, and the bill is arriving fast. Three moves from the last 24 hours show the industry pivoting from land-grab to margin. China's large model vendors are ending the price war, with DeepSeek leading the climb at API increases of up to 11x. DeepSeek's new peak/off-peak (峰谷) schedule puts output tokens at roughly $1.32 per million at peak hours and about $0.66 off-peak, while

Slack launches Slack Code for vibe-coding with AI agents

Three threads from today's feed: collaboration tools are bending toward agents, a founding figure of reinforcement learning is questioning the field's favorite shortcut, and the cybersecurity job market is splitting along an experience line. Slack Code turns chat channels into shared workspaces for coding agents. The new feature gives teams dedicated, project-specific channels where anyone can tag in a coding agent — Anthropic's Claude or Cognition's Devin — to build a feature, fix a bug, or up

Meta's AI appetite turns it into a top Microsoft Azure customer

Two product launches and a privacy reckoning lead the AI desk today. Meta is now one of Microsoft's largest AI customers, spending hundreds of millions of dollars a year on Azure to run trillions of AI tokens every week. According to a Bloomberg report carried by Techmeme and reposted across Chinese outlets, Meta's own AI ambitions have made it a major buyer of rival Microsoft's cloud — a striking turn for a company building its own data centers and custom AI silicon. The scale is eye-watering:

Anthropic runs an internal 'Model 2' stronger than any public Claude

Two stories today point at the same quiet truth: the most interesting AI isn't always the version you can log into. Anthropic is running a model more capable than any Claude you've met — and a freshly funded startup is betting that video's next form is code, not pixels. Anthropic is quietly running an unreleased model internally that beats every public version of Claude. According to the company's August 2026 Risk Report, the model — codenamed "Model 2" and placed in the Mythos class — scores a

Nvidia pursues $20B stake in Mercor, its AI training-data supplier

Nvidia is moving to take a direct financial stake in the company that already feeds its own models — a signal that the chip giant now treats training data as strategically captive as silicon. Nvidia is in talks to lead a round that would value Mercor, an AI training-data supplier, at roughly $20 billion — double the $10 billion it commanded just weeks ago. According to a Bloomberg report, the chipmaker is weighing an investment that would make it both a major backer and a key customer of the st

Binance lets AI agents trade real money on its exchange

Two moves today show the AI-agent economy maturing fast — one putting autonomous software directly in charge of real money, the other raising hard questions about how real China's robotics boom actually is. Binance has launched Agent OS, a platform that lets AI agents analyze markets and execute trades on users' behalf using real money. The world's largest crypto exchange, with more than 300 million registered users, opened the platform Thursday, wiring agents into Binance's APIs, wallet infras

China's robot industry books a record 165.5B yuan first half

China's robotics sector just posted its strongest half on record as the 2026 World Robot Conference opened in Beijing — and the executives on stage are already rethinking what the business model looks like once the machines can actually do the work. China's robot industry hit 165.5 billion yuan in H1 revenue, up 24.5% year over year. At the Aug 19 opening of the 2026 World Robot Conference in Beijing, MIIT vice minister Xin Guobin said the country's robotics industry is now scaling fast: full-y
